I think i have been overboosting my motor. i have the duty cycle at 100% but monitored my kpa. the scanner went up to 255kpa real fast a little to fast
i thought at 255kpa it bled off rest of the boost till the turbo started to make a weird noise. I thought it was blown, so i checked the charge pipe
and no oil or smoke out the tail so i reflashed the ecm to stock gmpp and it seems fine, except under high boost?
